Scientist 2

Scientist 2 is a 2005 Doom II megawad by Roland van der Velden (Scientist). Built off a 2002 release called simply Scientist, which contained the first 11 maps, Scientist 2 contains those same levels plus 9 new single player levels (for a total of 20), together with 10 bonus deathmatch levels based off the single player ones.

The player journeys through a city, a Soviet base in Siberia, and finally a series of ancient ruins to track down and kill the main antagonist of the story: a scientist seeking to gain immortality through his experiments.
